Macrophages express pattern recognition and cytokine receptors that mediate proinflammatory signal transduction pathways to combat microbial infection. To retaliate against such responses, pathogenic microorganisms have evolved multiple strategies to impede innate immune signaling. Recent studies demonstrated that YopJ suppression of TAK1 signaling during Yersinia pseudotuberculosis infection promotes the assembly of a RIPK1-dependent death-inducing complex that enables caspase-8 to directly cleave and activate gasdermin D (GSDMD).

This ability is also essential for the effective management of insect pests, including tephritid fruit flies, using the Sterile Insect Technique. Here we apply transcriptomics and proteomics to male reproductive tissues before and after mating to characterize components of semen that might mediate remating inhibition in Queensland fruit fly.
